New Army models predict number of cyberattacks that pierce company networks

Researchers developed a predictive model to estimate the number of successful cyber intrusions, which found that internal security policies and network access patterns are strong predictors. The model's accuracy was improved by analyzing regression results and demonstrated the feasibility of constructing a practical predictive model.

Monk parakeets invade Mexico

A recent study reveals that nearly half a million monk parakeets were imported into Mexico over five years, leading to rapid expansion across the country. The species was declared an invasive species in 2016, highlighting the need for management steps.

Urban development in ancient Rome

A study by Hugo Delile and colleagues used high-resolution geochemical and isotopic analyses to reconstruct Rome's urban development. The analysis of a sediment core from Ostia harbor revealed the installation of ancient Rome's lead pipe system was around 2nd century BC, with a peak during the early-high Imperial period.

An eye towards islets

Scientists at University of Pittsburgh create vascularized pancreatic islet organoids using human pluripotent stem cells, offering potential treatment for Type I Diabetes. The innovative approach involves implanting blood vessel fragments into the islets before transplantation.

High-resolution modeling assesses impact of cities on river ecosystems

A new study uses high-resolution geospatial modeling to quantify the effects of urban infrastructures on US rivers and streams. The research found that urban land transformation and electricity production together affect seven percent of U.S. streams, influencing habitats for over 60 percent of North American freshwater fish species.

Going to extremes to predict natural disasters

Researchers at KAUST have developed a systematic method for comparing the accuracy of different types of simulation models for predicting extreme events. The study found that nonparametric methods are more flexible but limited to small dimensions, while parametric methods can handle higher-dimensional problems but are sensitive to errors.
